The park exhibits the massive grandeur of the Rocky Mountains. Trail Ridge Road crosses the Continental Divide and looks out over dozens of peaks that tower more than 13,000 feet high. Longs Peak, the highest peak in the park, is 14,259′ in elevation. The high point on Trail Ridge Road is 12,183′. The road is closed from late fall, to the Memorial Day weekend. Because of the high elevation of the park (8,000′ to over 14,000′) visitors need to take time to acclimatize. People with various medical problems should check with their physician before coming to the park. Elk, mule deer, big horn sheep, moose, coyotes and a great variety of smaller animals call the 416 square miles (265,769 acres)of the National Park home.
